How do I enable cross-save between different casino platforms?

Cross-save for casinos involves harmonizing data storage. To achieve this, you must build a master player accounts database that communicates with the backends of your casino’s systems. By using RESTful APIs or GraphQL, you can establish a centralized data repository where players’ information – including game status, balances, and rewards – resides.

First, you’ll require APIs for Player Accounts, Game Progress, and Transactions, which allow for GET/PUT of player data, synchronization of game state, and tracking of in-game events, respectively. The platform will include appropriate authentication services (e.g., OAuth 2.0) to ensure the security of player sessions.

For instance, large casino operators such as Playtech and NetEnt have cross-save functionalities in place within their suites of games. They generally rely on standard data formats (JSON, for example) to ensure that data from a mobile, desktop, or even a live game is saved and loaded consistently. One particular hurdle is updating the data in real time without interfering with an ongoing game. I would suggest you check out their open platform APIs for cross-save-specific implementations.

Casino cross-save will require backend synchronization. Need to expose the backend APIs (REST/GraphQL) for each platform. OAuth 2.0 for authentication. Need middleware to coordinate the API calls and keep the state synchronized in realtime. See how other providers do it - NetEnt, Playtech etc. Most probably have standard backends from OneStop or GAN. Have to be careful with security. Unity should have some network stuff if you are using them. Try with a few platforms first and test the hell of it.
